First, iron oxide is not a dangerous chemical, but an iron oxide, not to mention ferric oxide (Fe2O3), mainly containing iron ions, and iron ions are not toxic, iron is an essential element of the human body, so the food plus The iron oxide red food will not be harmful to the human body, because the iron oxide red with the formation of ferric chloride, non-toxic, so iron oxide is not toxic; but we have to dialectically see the problem, if the intake too much , By the dissolution of gastric acid generated by the ferric chloride ionization of iron ions beyond the human standard, it will make people poisoning, so consumption of iron oxide red food should not be excessive.

Iron oxide can be added as a feed additive to the livestock to help the growth of animal animals, such as health can be made to supplement the pigeons in the feed intake of nutrients and trace elements, is very conducive to pigeon digestion, the specific formula is: 25% of sand, shellfish (diameter 0.8 cm below) 20%, gypsum 5%, salt 3%, old lime 5%, charcoal 5%, trace element additive 7%, bone meal (fry) 15%, loess 10 %, Gentian grass 1%, licorice 1%, egg yin 1%, pecking feather 1%, 0.5% of a variety of vitamins, red iron oxide 0.5%.

Iron oxide is a non-polluting environmentally friendly products, but in the production process, it will inevitably be some harmful substances, such as will produce a lot of iron oxide dust. Long-term inhalation of this production of dust, can cause flu-like symptoms of metal smoke, including inflammation, chills, chest tightness, cough, mouth metal taste. Followed by eyelid irritation, permanent eye conjunctival staining, bronchitis and chronic cough. And then cause “iron-tail”, also known as “iron pneumoconiosis.” In order to avoid this harm to the human body, the production process to pay attention to respiratory protection, such as wearing self-contained positive pressure full facepiece respirator, air supply positive pressure full facepiece respirator supplemented by self-contained positive pressure breathing and so on.

The production of iron oxide red for the manufacturers of production technology and equipment requirements are very strict, for the production of harmful substances, to be promptly dealt with, can not give people around the center of the impact of harm. If the substance or contaminated fluid enters the waterway, notify downstream users of potential water pollution, notify local health, fire officials and pollution control departments to properly handle the environmental impact of the hazard.

On the other hand, iron oxide red on the current has a lot of resistance, can absorb water, can be conductive, it may become a dangerous reason for the use of electrical appliances, resulting in poor current, resulting in short circuit and so on. This can directly harm people’s lives, so we pay more attention to work and life.

The largest consumer sector for iron oxide pigments is the construction and coating industry. The rise and fall of these two industries and direct changes in demand for the region’s consumption situation. In recent years only for color mortar iron oxide in more than 7,000 tons per year. In addition to paving materials, the Western European concrete roof tiles, concrete prefabricated parts, concrete blocks, colored bricks, color mortar, also need a lot of iron oxide pigments. In North America, Canada is influenced by European style, iron oxide consumption structure similar to that of Europe, Canada and Australia iron oxide pigments are also mainly used in the construction industry in Western Europe 60% of iron oxide for building materials. Such as the United States in the annual consumption of 50,000 tons there are 30,000 tons for the construction industry; British concrete flooring materials with iron oxide at an alarming rate of growth. 65% of Canada’s iron oxide products are used in the domestic concrete industry and 10% for colored concrete mortars. In the Australian iron oxide pigments in the annual trading volume of 20,000 tons, its demand with the number of new buildings and ups and downs. The United States in recent years by the European market, the construction industry, the amount of iron oxide pigments with the rapid development of the industry is also increasing, about synthetic iron oxide 40,000 to 50,000 tons of annual consumption. US iron oxide in the building materials sector is mainly used for concrete paving blocks (about 15% to 20%) with a large number of iron red, yellow, iron, iron and black manufacturing of colored concrete products. For building construction, iron brown, iron black in China is the most popular building materials colorants. In short, the foreign iron oxide consumer market, whether it is the existing market or potential market, are mainly subject to the demand for colored building materials control. In the country, most of the iron oxide pigments are used in building materials, the amount of about 60% of total sales. Mainly applicable to the following various building structures and concrete products, coloring:

As a result of good weatherability, alkali resistance, light resistance (these properties are not other inorganic pigments or organic pigments can both), so in the building materials are used in iron oxide pigment as a coloring agent, in the amount of concrete products in the limit Below 10%. (The amount of natural products can be more than some) more than the high limit will make the mechanical strength of products decreased, and affect the solidification time. Generally 4 to 8% is appropriate, while iron oxide pigments without cobalt, zinc oxide, it will not affect the solidification time and solidification strength.
